Open3D It's an open source library , Support rapid development processing 3D Data software .Open3D Front end use C ++ and Python A set of carefully selected data structures and algorithms are disclosed . The back end is highly optimized , And set to parallelize .Open3D Has two interfaces ：C ++ and Python. This tutorial focuses on Python Interface , Because it's easy to use , Should be regarded as Open3D The main interface of .

conda Usually and numpy And other common libraries , Application conda When installing, you need to enter ：

pip3 install open3d-python

Many are omitted , Here we are open3d The library is installed successfully
